To all whom it may concern:

Be it known that I, JOHN P. l-IAssEL- MEYER, a citizen of the United States, and a resident of the borough of Bronx, city and State of New York, have invented certain new and useful Improvements in lVindows, of which the following is a specification.

In the construction of the modern sky scraper buildings in congested cities, it has been demonstrated that the windows can be cleaned; removed from the window frame for repairs, and also to permit an unrestricted opening of the window, only at the risk of great danger to the operative and to the public on the street beneath the window.

My invention is designed to overcome these objections by means of a simple mechanical construction which can be easily applied to the windows now in common use. One of the objects of my invention, therefore, is to produce a construction of window frame and window sash by means of which I am able to turn the sash. around for washing on both sides thereof so that the person washing the window may work at all times within the building. When the sash is turned for washing, the window is closed so that there will be no draft in the room and the person doing the work will not be exposed to the weather.

Another object, of my invention is to so construct a window that the sashes and the part of the frame carrying the sashes can be easily and readily removed as a whole from the main portion of the frame so that large articles such as safes, pianos, &c., can be moved through the window. Another object is to provide a construction by means of which the partsof the window frame, sash, cords, 620., can be easily reached and repaired.

Another object is to so construct the sides of the window frame that when the part of the frame on the inside is opened the corre-' sponding part on the outside will be automatically opened so as to permit the turning of the sash and removal of the part of the frame in. which the sash slides and is balanced. Another object is to provide an arrangement of window cords and weights so that the sash can be turned more easily, and the weights may be much lighter than those required for the ordinary construction. Other objects will appear from the hereinafter description.

The preferred form of my invention is which Figure 1 is a front elevation of my-improved window, viewed from the inside in which all of the parts are in a closed position.

Fig. 2 is a front elevation viewed also from the inside, in which the sides of the window frame are shown in an open position and the sashesin the center of the structure, in the position to be assumed by them in order that the window may be turned around; or turned to remove the sashes and that part of the frame in which they are mounted from the fixed frame.

Fig. 3 is a section. of line 33 of Fig. 9., the window sashes being shown in a horizontal position.

Fig. 4 is a sectional view on line 4.4 of Fig. 8.

Fig. 5 is an end elevation of that portion of the removable part of the window frame showing the weights in their central position.

Fig. 6 is a sectional detail view on line 6 of Fig. 5.

Fig. 7 is a sectional view on line 7 of Fig. 6.

Referring to the drawing in which the same reference characters are used to indicate identical parts in all the views,

10 represents the fixed sides of the window frame, llthe sill and 12 the fixed top.

The inner and outer sides 13 and 14 respectively of the window frame are hinged at 15 to the fixed upright part 10, and each pair are operatively joined together by a connecting rod and lever construction, which may be of any suitable design.

For this purpose I employ levers 16 p11" oted at their center at 16 to the inner fixed sides of the window frame. On the inner side of the hinged upright portion of the frame are lugs 17, and connecting rods 18, are pivotally attached to the lugs 17 and to the opposite ends of the levers 16. Stop pins 19 are placed on the inner side of the frame to limit the extent of the movement of the lever.

By means of this construction, when the inner side of the window frame is opened inward, the outer side of the frame'is opened .outward, and similarly, the closing of the inner portion of the frame results in the closing of the outer portion. Secured to the outer portion of the frame on each side, are weather strips 20 each extending from the extreme top to the extreme bottom of the frame, thereby closing to the weather all seams and joints which would otherwise be open.

Pivoted buttons 21 are provided to hold the hinged sides of the frame in a closed position, or I may use any suitable latching mechanism for the purpose in lieu thereof.

Journal bearings 22 each having an open slot 23 are mounted opposite to each other at the center of the inner fixed sides of the frame.

The inner side of each frame containing the parallel grooves or ways 32 and 33 in which the window sashes 40 are mounted to slide is constructed preferably in these parts 34-, 35 and 36, the center part 85 of which is provided on one side with the parallel grooves 32 and 33 for the window sashes, and at the center of the other side with pivot pins 87 extended therefrom to fit in the slotted bearings 22. Fixed strips 88 extend on each side of the center structure to hold the same at the proper distance from each side of the frame so that the window sashes may properly slide in the grooves or ways provided therein.

These strips also form boxes or ways in which the weights to and the cords L1 and 42 are nested and may slide. Pulleys or sheaves 43 are mounted at the ends of the grooves on the center sectional frames, and what may be termed endless cords L1 and 12 are attached to the center of each sash and then pass in opposite directions through and over the pulleys at each end and meet at the center at the other side of the sectional frame where they are secured to the weight 40.

By means of this improved construction the weights will be prevented from falling out of place when the window is reversed, which function isnot present in those constructions in which the weight hangs free at the end of the window cord.

Upon the opposite sides of the frame the fixed sections 34;,and 36 are provided with grooves 50 and 51 therein which are in line with the grooves 32 and 33 in the center sections when brought in this central upright position. lVhen the window sashes are closed it is seen that they extend across the opening between the center section and the fixed upper and lower sections, and all the parts are thereby held in a closed position.

lVhen the sides of the fixed frame are opened, and the sashes are nested together in the center of the window they may be turned completely around through 180 and then each may be again raised or lowered to assume an upper or lower position. Upon turning the central section containing the window sashes to any angle so as to be clear of the fixed upper and lower grooved sections, the central sectional frames and sashes may be readily removed from the window frame for any purpose desired either to get at the parts to repair them, or to make a clear window opening so that large articles 'can be carried through the same.

The structure may be made of wood, -or of sheet metal such as is now frequently used in building construction. It is to be understood that the construction above described is limited in details only to the extent specified in the claims. 7

Having now described my invention, what I claim as new and desire to secure by Letters Patent is;

1. In a window, a stationary frame, a pair of swinging frames pivotally mounted therein, sashes sliding therein, a pair of weights for each sash, endless cords secured respectively to the sash and to each weight, said cords passing through leads mounted in swinging frames and at a distance from the pivots.

2. In a window, a stationary frame, a pair of swinging frames, pivotally mounted therein, window sashes, cords and weights, the cords and weights securing the sashes to the swinging frames. 7 r

3. In a window, a stationary frame, provided with fixed guides for the window sashes, av pairof swinging frames pivotally mounted in the stationary frame, said swinging frames forming guides for the window sashes in alinement with the aforementioned fixed guides, hearings in which the pivots of said frames are removably mounted, sashes mounted in said swinging frames, endless cords securing the sashes respectively to the swinging frames, uprights hinged to the sides of the.stationary frame to hold the swinging frames in upright position and their guides in line with the fixed guides, and means for holding the uprights in open and closed position. 7

In witness whereof I have hereunto set my hand at the borough of Manhattan, city and State of New York, this 19th day of August, 191st.
